To ALL WHOM IT- MAY CONCERN:

Be it known that I, JOSEPH .HECKEL, of Decatur, in the county of Macon, and State of Illinois, have invented a. new and useful Improved Composition for Covering WoodenBuildings, Bridges, etc.; and I do hereby declare the following to be a-full, clear, and exact description of the some.

The composition which is the subject of this invention is desi gned to render wooden structuresfire-proof, and to proteet them from the action of the water and of. th

e weather. It is also designed to be used its a. paint,

To manufacture this composition, I mix china-clay, oyster-shell lime, borax, and litha-rge, in the following undone pound of with boiled linseed oil till it attains the proper consistency. If desired Ordinary clay or lime may be used, but the composition will then be inferior in quality both as a/cem'ent and as paint. I design using, for practical purposes, the purest quality of china-clay and shell lime. I do not wish, however, to limit myself to these, but desire to beat liberty to use other qualities of clay and lime in their stead.

Having thus described my invention, what I claim as new therein, and desire to secure-by Letters Patent, is-

The composition above described, when eompounded and used-substantially as and for the purposes specified.

JOSEPH HECKEL.

This composition having been pulverized as fine as possible, and thoroughly intermingled, is mixed,

for fire or water-proof cement, itshould. be mixed to the eonsistency of paste; iffor paint, more oil will be required.
